Mobile truck repair is a service where a diesel mechanic drives to your truck’s location to perform repairs on-site. Instead of towing a broken-down commercial vehicle to a shop, the mechanic arrives with diagnostic tools, parts, and equipment to fix the problem wherever the truck is parked, whether that is a highway shoulder, loading dock, fleet yard, or job site.

Most mobile truck repair services work on Class 6 through Class 8 commercial vehicles, including semi-trucks, box trucks, dump trucks, flatbeds, tankers, and refrigerated trailers. Many also service medium-duty trucks, delivery vans, and specialty commercial vehicles. Common brands serviced include Freightliner, Kenworth, Peterbilt, International, Volvo, Mack, and Western Star.

Many mobile truck repair providers offer 24/7 emergency service, though availability varies by company and location. The featured providers on Mr. Mobile Truck Service are selected in part for their availability, especially after-hours. When searching for service late at night or on weekends, call the featured listing first as they are most likely to have emergency dispatch capability.

Most common truck repairs can be performed on-site: engine diagnostics, brake jobs, electrical troubleshooting, starter and alternator replacement, air system leaks, coolant leaks, fuel system issues, DPF regeneration, and tire service. Repairs that typically require a shop include major engine overhauls, transmission rebuilds, frame work, and anything requiring a vehicle lift or alignment rack. A good mobile mechanic will tell you upfront if the job needs a shop.
